Attack: OS Credential Dumping: Security Account Manager
Adversaries may attempt to extract credential material from the Security Account Manager (SAM) database either through in-memory techniques or through the Windows Registry where the SAM database is stored. The SAM is a database file that contains local accounts for the host, typically those found with the net user
command. Enumerating the SAM database requires SYSTEM level access.
A number of tools can be used to retrieve the SAM file through in-memory techniques:
Alternatively, the SAM can be extracted from the Registry with Reg:
reg save HKLM\sam sam
reg save HKLM\system system
Creddump7 can then be used to process the SAM database locally to retrieve hashes.(Citation: GitHub Creddump7)
Notes:
- RID 500 account is the local, built-in administrator.
- RID 501 is the guest account.
- User accounts start with a RID of 1,000+.
